Research Objective
To design a mode-matched MEMS vibratory gyroscope with electrostatic frequency tuning and capacitive readout using COMSOL Multiphysics.
System Architecture
The model can include drive and sense masses, suspension beams, tuning electrodes, capacitive sensing gaps, electrostatic field setup, structural mechanics and coupled multiphysics studies.
Simulation Methodology
Eigenfrequency, electrostatic tuning and harmonic response studies are used to align drive and sense modes, quantify tuning voltage effect and estimate capacitive readout sensitivity.
Validation Scenarios
- base-case model setup and parameter verification
- main design or control case under rated operating conditions
- parametric change to prove robustness and sensitivity
- comparison with baseline or conventional method
- result discussion for thesis, paper and project-report writing
Expected Graphs and Result Discussion
A complete result section should include the main waveforms, model outputs, field plots or comparison tables needed for engineering thesis documentation. For this project, the important graph set includes:
- drive and sense mode shapes
- mode-matching frequency split
- electrostatic tuning voltage curve
- capacitive readout displacement response
- stress and deformation under excitation
Thesis and Research Extension Ideas
The topic can be extended for journal-style novelty by adding optimization, robustness studies, comparative analysis, hardware-aware constraints or application-specific validation.
- quadrature error reduction
- closed-loop drive/sense electronics model
- fabrication variation sensitivity
- noise and bias stability estimation
